Answer:
y = 40/3
Step-by-step explanation:
For greater clarity please write 3y-8/12 =y/5 as:
3y-8 y
-------- = ------
12 5
Cross-multiplying, we get:
15y - 40 = 12y
Combining the y terms yields 3y = 40, so that y = 40/3
Answer:
31465 ways
Step-by-step explanation:
Given data
Let us apply the combination formula
nCr = n! / r! * (n - r)!
n= 31
r= 4
substitute
= 31!/4!(31-4)!
= 31!/4!(27)!
= 31*30*29*28*27!/ 4!(27)!
= 31*30*29*28/4!
=31*30*29*28/4*3*2*1
=755160/24
=31465 ways
Hence there are 31465 possible ways to rank it
